The Calibrated Stumble.

In late April 1961, John F. Kennedy walked off the worst week of his young presidency — the Bay of Pigs invasion had collapsed in fewer than 72 hours — and watched his Gallup approval climb to 83%, the highest of his time in office.

That oddity has a name in social psychology: the pratfall effect. Done well, a small, well-placed stumble can humanize a high-status communicator and make them more — not less — persuasive. Done poorly, it just looks like incompetence.

This month's newsletter covers:

  • The 1966 College Quiz Bowl study that first isolated the effect — and why the result hinges entirely on the perceived competence of the person doing the stumbling.
  • Why the same small mistake helps one leader and quietly damages another — the contingencies around self-esteem, severity, and (per Brescoll & Uhlmann) gender that turn a pratfall into a pitfall.
  • A 2025 study of 350 B2B sales managers showing the calibrated stumble is a double-edged signal — and four imperatives for using it without cutting yourself.
